Make sure the UEPO Cable status is redundant by sending a UEPO Panel/Cable redundancy command to the BPCH
FSP. To do this access the
HMC BPC-A ASM SIDE_A
Service Processor Command Line (Refer to ‘Power775
BPC FSP Command Line Procedure’ in Appendix A of this PDF and ensure
ASM SIDE_A
is active per Step 12)
and enter the following at the command prompt (IMPORTANT: DOUBLE-CHECK THE COMMAND IS TYPED
IN EXACTLY CORRECT BEFORE PRESSING ENTER BECAUSE EVEN A SINGLE INCORRECT
CHARACTER COULD RESULT IN SEVERE UNINTENDED SYSTEM DISRUPTION!!):
bpccmd -c 9baa0000ffef
Expect 00aa00 returned which means the command executed properly
and reported successful “Redundant UEPO Panel/Cable” status.
If something different is returned, then contact the next level of support. For reference, the returned “rrssdd” format
hexadecimal characters can be translated as follows:
“rr” Return Code Definitions:
00 = Command executed properly
21 = Cage Not Present / Configured
22 = FRU Not Present / Configured.
27 = Location code error
43 = Not valid for this FRU
96 = Mail-boxing error
“ss” Sequence Number:
aa = Arbitrary and unimportant
“dd” Return Data Definitions:
00 = Redundant status. It is OK to replace the UEPO Cable and continue with Step 9
01 = Non-redundant status. It is NOT OK to replace the UEPO Cable. Please contact next level of support
